There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE MIDDLE MISSISSIPPI VALLEY SUMMARY Isolated severe storms capable of hail and gusty winds are possible mainly this evening across northern/eastern Missouri into south-central Illinois. Northern/eastern Missouri into south-central Illinois Airmass modification and modest-caliber moist advection will occur north-northeastward into the region along and south of a decelerating southeastward-moving front. The limited low-level moisture, coupled with strong heating and mixing, should keep the airmass across the region capped through the afternoon. However, toward/after sunset, sufficient moistening atop the decoupling boundary layer should support increasing thunderstorm development this evening. Convection will tend to be rooted around 750-850 mb, and while elevated buoyancy will not be robust, the steep lapse rates could yield some severe hail (and possibly gusty winds) in the presence of 40+ kt shear through the cloud-bearing layer. Far South Florida While a couple of strong storms could occur through the afternoon, cloud cover and an increasingly prevalent post-frontal regime, along with weak lapse rates in the cloud-bearing layer, should tend to limit storm intensity inland. Northern California/southwest Oregon Thunderstorms are expected along the northern periphery of the upper low off the central California coast. Increasing mid-level moisture and cold mid-level temperatures will support modest buoyancy amid moderate easterly flow aloft, supporting the potential for small hail and gusty winds with these westward progressing storms during the late afternoon and early evening. However, organized severe storm potential is expected to remain low.

Pollen Index: 10.3 Pollen Level: high Predominant Pollen: Maple, Birch and Oak. The amount of pollen in the air for Monday will be falling but will remain in the high range. This forecast of lower pollen concentration is based on rising humidity and expected precipitation in the morning and evening which tends to wash pollen out of the air.
